Lyssa Dennis Standing in the shoes

For some reason, when thinking of foreground/background, I immediately
thought of actors on a stage.  The columns are further away from the audience,
showing the perspective, getting smaller and smaller as they go back.  The man
in front can be seen more easily because he's been colored darker, while the girl
in the back is lighter because she's further away.  The lines on the stage serve
as the lines guiding the eye to the vanishing point, which is at the back of the
stage.
